DESCRIPTION

OPTIONS

GIT_EDITOR

$SOME_ENVIRONMENT_VARIABLE, "C:Program FilesVimgvim.exe" --nofork. The order of preference is the $GIT_EDITOR environment variable,
then core.editor configuration, then $VISUAL, then $EDITOR, and then finally vi.
GIT_PAGER

$GIT_PAGER environment variable, then core.pager configuration, then $PAGER, and then finally less.
